Another group in our department mounts web folders out of users home afs 
I recently moved several thousand  user vols from one afs server to 
another using vos move.
The folks running the web server reported that several of these 
mountpoints were timing out on them.
This has happened before.
I had them run fs flush , flushmount, and flushvolume and still the 
timeout continued. Stopping and starting the client fixed it.
So I  looked again to make sure that ports 7000~7010 were open on the 
They were. Could this be an issue with the clients firewall perhaps? 
Seems to me the volserver calls back to the client when something 
changes. Is there a recommended port range for afs clients that needed 
to be opened for incoming udp traffic?
We are running version 1.4.2 server software. I don't know his client 
version but I can find out if needed.
